Links

Many links have title attributes that describe the link in greater detail, unless the text of the link already fully describes the target.

Whenever possible, links are written to make sense when read out of context. Many browsers (such as JAWS, IBM Easy Web Browsing software, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list separately from the page.

Link text is never duplicated; two links with the same link text always point to the same address.

There are no javascript: pseudo-links. All links can be followed in any browser, even if scripting is turned off.

There are no links that open new windows.

Visual design

This website uses cascading style sheets for visual layout.

The stylesheet uses only relative font sizes, which are compatible with the user-specified “text size” option in visual browsers. For example, in Internet Explorer you can make your default text size larger under the View menu by selecting Text Size, Larger (or Largest).

If your browser or browsing device does not support stylesheets, the content of each page is still readable.
